Richard E. Engler, Ph.D. is Director of Chemistry with Bergeson & Campbell, P.C. (B&C®). Dr. Engler is a 17-year veteran of the U.S. Environmental Protection Agency (EPA) and is one of the most widely recognized experts in the field of green chemistry, having served as senior staff scientist in EPA's Office of Pollution Prevention and Toxics (OPPT) and leader of EPA's Green Chemistry Program. He has participated in thousands of Toxic Substances Control Act (TSCA) substance reviews at EPA, as well as pre-notice and post-review meetings with submitters to resolve complex or difficult cases, and he draws upon this invaluable experience to assist B&C clients as they develop and commercialize novel chemistries.

Dr. Engler's expansive understanding of the specific challenges and opportunities TSCA presents for green and sustainable chemistry is a powerful asset for clients during regulatory review. He assists clients in performing toxicological reviews, performing environmental fate modeling using Sustainable Futures tools, and preparing scientific and test data for regulatory submission. He is particularly skilled in preparing Pollution Prevention (P2) statements to highlight the concrete environmental benefits of biobased or renewable chemicals, as well as other sustainable chemistry products and processes.

Representative Engagements:

Prepared an Optional P2 Statement for a premanufacture notice (PMN) submitted by a leading global specialty chemical company that lead to a determination of reduced relative risk and a no Section 5 regulatory action on the PMN substance.

Responded to concerns raised during review of a PMN submitted to reduce a risk-based, up-front ban to a non-risk-based Significant New Use Rule (SNUR).
